Hi folks,
I am getting a nasty exception on the server side when working with ROP.
It occurs in very specific circumstances: I create a new object, save it
back to the server. When I try and look at that object again, I get the
exception below.
My insert process is basically context.newObject, and then set the
relationship from the existing object to point to the new one.
The odd thing is that the SQL logs show that the DB query works
perfectly: the correct number of records are returned without a problem.
And even more strangely, if I restart the servlet it works perfectly.
Also, I think it is new since moving to 1.2 (90% sure).
Any ideas? I don't know where to start on this one.
Regards,
Marcel
